ST. LOUIS - The U.S. government says Tyson Foods has agreed to pay roughly $4 million in civil penalties to settle alleged violations related to eight accidental releases of anhydrous ammonia that happened over a four-year span and caused one death.

The Justice Department and Environmental Protection Agency says the deal in a St. Louis federal court with the nation's biggest meat company involves alleged Clean Air Act violations at Tyson sites in Missouri, Kansas, Iowa and Nebraska.
